Bakr et al. reported the flow reactor synthesis of PbS quantum dots for applications in solar cells. They showed that the flow reactor products had comparable performance to the batch synthesized PbS nanoparticles. A dual-temperature-stage flow reactor synthesis was carried out to achieve optimum results. The flow reactor system is shown schematically in Fig. 11. In this method precursor A consists of lead oxide, oleic acid (OA), and octadecene (ODE) whereas precursor B contains bis(trimethylsilyl) sulfide (TMS) and ODE. The two precursors are injected under nitrogen. The mixed reactants proceed together to the nu-cleation stage that is temperature-controlled by thermocouple 1. The precursors react at the elevated temperatures to form nucleation seeds. The quantum dots are then isolated using acetone and re-dispersed in toluene. 

The GDL is usually made of a carbon-based porous substrate, such as carbon paper or carbon cloth, with a thickness of about 0.2 to 0.5 mm and a dual-layer structure. A schematic of the GDL between the flow field and the catalyst layer is presented in Figure 1.13. The first layer of the GDL, in contact with the flow field and the inlet gas in the flow channels, is a macro-porous carbon substrate, serving as a current collector, a physical support for the catalyst layer, and an elastic component of the MEA. The elastic component is necessary for the fuel cell to handle the compression needed to establish an intimate contact. The second layer of the GDL, in contact with the catalyst layer, is a thiimer microporous layer consisting of carbon black powder and some hydrophobic agent, which provides proper surface pore size and hydrophobicity to avoid flooding and to enhance intimate electronic contact at its interface with the catalyst layer [33]. 

In addition to in situ XRD, powerful in situ TEM techniques for monitoring electrochemical reactions in real time have recently been developed. These experiments involve the use of a specialized dual-probe electrical biasing TEM holder on which a nanoscale electrochemical cell is fabricated, as shown in the schematic in...
